f �s aJ Corbitt said an important component for the program is the collaboration among County divisions and the State to provide groundwater data and pollution source locations to the public via the Internet : ❑ Private wells including new wells and existing wells ❑ Public water supply wells , including community wells , transient non - community wells and non - transient non - community wells ❑ Contaminated wells ❑ Monitoring wells ❑ Irrigation Wells ❑ Registration of well drillers and pump installers Based on Mecklenburg County local investigations , 24 % of the wells have some type of bacterial contamination and 3 % of the wells sampled have some type of volatile organic compound contamination : ❑ 214 wells exceeded the USEPA drinking water standards with contaminants that were Volatile Organic Compounds ( as of December 2002 ) ❑ 321 wells were identified as being contaminated testing positive for bacteria ( from 1999 to 2002 ) ❑ Estimates that 70 , 400 homes have wells ( 20 - 300/o of population ) ❑ Number of contaminated wells is unknown because not all wells in the county have been identified Volatile Organic Compounds were identified and described as : ❑ Compounds like gasoline , solvents , degreasers , ❑ Used in a variety of commercial and industrial applications ❑ Found in household products ❑ Move freely between the soil , air surface , water and groundwater Corbitt suggested that a comprehensive program might include : • Registering existing wells to document location and uses sampling to document a safe drinking water source • Permitting new wells to document location , proper construction ; sampling to document a safe drinking water source • Registering community wells ; submitting existing sampling data to local government and centralize sampling data • Providing temporary drinking water for contaminated private wells • Sampling contaminated wells after homeowner installs a treatment system Corbitt said the 2002 Mecklenburg Priority List reported 1120 contaminated sites . Other possible approaches were identified as monitoring wells by : • Registration • Monitoring well fee • Contamination assessment fee • Establish well abandonment requirements Corbitt described a possible timetable of events for a local well ordinance , as it is important part of a comprehensive groundwater program : Page 3 of 8 DRAFT
